Assignment: Powerpoint Training Assignment
You are tasked to provide a briefing to newly assigned forensic laboratory technicians. They have experience in using instrumentation, but no experience in processing the items common to a police crime lab.
This briefing is about hair samples and use of the microscope in analyzing hair. Specifically, during a microscopic comparison of two hairs, a trace analyst compares the medullae of the hairs to determine species of origin and, if possible, human origin of the hairs.
At a minimum, cover the following topics:
• Demonstrate the difference between the medullae of human and animal hairs.
• Name and show one exception to this among humans that may help in these determinations.
• Explain how to differentiate between Caucasoid, Negroid, and Mongoloid hair samples.
